Deburring is the process of removing all burrs. The burr is a process in which a raised edge or small metal piece remains attached to the workpiece. Deburring is an essential finishing process for any CNC operation. This article mainly introduces the method of desktop cnc mill deburring, please browse below.
People often overlook the importance of knowing the full size of the burr. Thickness is the biggest issue. Long burrs are usually easy to remove, but burrs that are longer than it are much thicker. The thickness of the burr is difficult to measure; it may be necessary to use a measuring microscope or make the part into a rubber mold, cut it into thin slices, and then measure the burr with an optical comparator.
Part size and shape are a problem, and certain areas of the part may be prone to burrs, such as sharp low-angle corners. For parts with burrs of different sizes at different positions, there is a danger that the overall excessive burr is removed by the deburring method and only the largest burr is removed. All deburring methods not only remove burrs, but also may lose critical dimensions during processing.
Factors that control the formation of burrs
The formation of burrs is a key issue in the industry. It is almost impossible to avoid the formation of burrs after processing. Only by changing the feed rate, cutting speed and tool geometry, the formation of burrs cannot be avoided. Burrs in the borehole play an important role in product quality and can cause reliability issues and performance degradation. Burrs are formed at the entrance and exit of the workpiece. Export burrs are important because they are larger in size and the most difficult to remove, causing burr problems. Therefore, many studies have focused on the burr drilling and milling operations at the exit.
Machining center deburring
Summarize several factors that control the formation of drill burrs. The following are the main factors for the formation of milling burrs:
Machining parts (geometry, size, mechanical properties, etc.).
Cutting parameters (cutting speed, feed rate, cutting depth, etc.).
Cutting tools (material, shape, geometry, rake angle, lead angle, helix angle, etc.).
Machine tools (speed, dynamic strength, etc.).
Manufacturing strategy (tool path, coolant, post-cutting, lubrication, MQL, etc.).
However, due to the complex interactions between process parameters, this overview is still limited, as their degree of influence on burr formation can be significantly changed only by adding or deleting cutting parameters and/or changing materials. In other words, the factors that control the formation of burrs cannot be easily divided into direct factors and indirect factors
Advantages of machining center deburring
Floating deburring method: It is mainly installed in a CNC machining center or robot, and can automatically remove burrs. It allows the floating mechanism and the tool to perform the following processing on the workpiece burr, and can flexibly remove the burr, not only does not damage the surface quality and accuracy of the workpiece, but also reduces the error caused by the positioning of the workpiece, which plays a very important role in reducing the difficulty of programming. Great effect. In addition, this set of equipment has good performance in automatic tool change and multi-step processing, and it is easy to use in CNC machining centers.
In addition, floating deburring also has the following advantages:
1. Ensure that the appearance of the workpiece is beautiful: With the help of a floating mechanism, the tool can automatically perform radial or axial offset according to the actual shape of the workpiece. This not only ensures the beauty of the workpiece, but also keeps the deburring effect consistent. It can also avoid uneven burrs and complicated procedures of rigid spindles.
2. Save processing time and labor cost: Floating deburring avoids time-consuming and laborious manual grinding and deburring. The whole process is automated, which not only saves time, but also improves the accuracy of the workpiece. Many traditional processing companies rely on manual grinding for deburring, which not only wastes processing time, but also increases labor costs. The use of floating deburring can save labor costs and reduce the failure rate of parts caused by manual operation errors.

3. Improve work efficiency: The installation of floating deburring equipment is very simple. It can be directly installed on the machine without any additional equipment. It is also easy to disassemble and replace, saving installation time. It is equipped with a high-speed pneumatic spindle. Effectively remove burrs, burrs and overflow, thereby improving processing efficiency.
4. Strong processing stability: For different materials, the floating deburring equipment can preset floating pressure according to different materials, so that the processing process remains stable.
